This metamorphic rock undergoes such high pressures and temperatures that the minerals crystallize and give way to a shiny natural plate.

Years of sedimentation are needed to create consolidated limestone. They are light colored, from white to grey, and older than humanity itself.

They are the product of fire and are born under our feet, which is why they capture so much power and depth. It is a resistant, erratic, long-lived stone.

This mineral stone, the color of sand, is usually located near hot springs. It arises from where water and earth become one.

Originating from the steaming vapors of a volcano, this semi-precious stone is made up of multicolored bands of chalcedony.

An unusual species both for its high quartz content and for occurring in unusually thin soils. Metaphorically, metamorphic.

Sedimentary rock consisting of sand or quartz grains cemented together, typically red, yellow, or brown in color.
